“I Have a Dream” is a public speech delivered by American civil rights activist Martin Luther King Jr. during the march on Washington for jobs and freedom on August 28, 1963, in which he calls for an end to racism in the United States and called for civil and economic rights. Delivered to over 2,50,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, D.C., the speech was a defining moment of the civil rights movement. Beginning with a reference to the Emancipation Proclamation, which freed millions of slaves in 1863, King observes that: “one hundred years later, the Negro still is not free”. Towards the end of the speech, King departed from his prepared text for a partly improvised peroration on the theme “I have a dream”, prompted by Mahalia Jackson’s cry: “Tell them about the dream, Martin!” In this part of the speech, which most excited the listeners and has now become its most famous, King described his dreams of freedom and equality arising from a land of slavery and hatred. Jon Meacham writes that, “With a single phrase, Martin Luther King Jr. joined Jefferson and Lincoln in the ranks of men who’ve shaped modern America”.

The average life span of humanity throughout all history was twenty seven years. In the 19th century, however, science and improved technology treble life expectancy. As technological capabilities improved and life expectancy increased, the number of babies per family went down, demonstrating the fact that nature keeps on balancing the population figure. After major wars, when large number of young and healthy men are Killed, baby-making increases. The birth-rate continues to rise for five years or so after wars end, until the score is rectified. All this happens without conscious cooperation or even the knowledge of the humans concerned. When the probabilities of human survival are poor, nature makes many babies.
